AppStream MetaInfo Creator
AppStream is a cross-distro effort for providing metadata for software in the Freedesktop ecosystem. It provides a convenient way to get information about not installed software, and is one of the building blocks for software centers.
This web application provides an easy way to generate good initial metadata for some software types to represent them in software centers or to provide additional metadata for systems. Users just have to answer a few questions to get started with creating AppStream MetaInfo/AppData files.
Users can use the production instance hosted at Freedesktop.org to generate their metadata. All metadata generation happens locally in the browser, no data is transferred to Freedesktop.
The MetaInfo Creator is an Angular (9+) web application intended to make it very easy for users to generate MetaInfo files to ship with their software.
